Capacity: 610 Grams Sensitivity: 0.1 Grams Calibrations: Front Beam - 10g x 0.1g, Center Beam - 500g x 100g, Rear Beam - 100g x 10g Adam's Triple Beam is today's best value for teaching mass measurement concepts from a brand scientists worldwide have trusted for over thirty years. It offers the functions and durability you need in a generous 2610g capacity plus an array of special classroom features that you will appreciate. With a larger overall body than other triple beam balances, it's the sturdiest choice for the classroom. Quality construction with strong metal housing and a stainless steel pan. Innovative built-in tripod legs allow you to do density demonstrations wherever you want (without the inconvenience of having to clamp onto a table.)
This kit can be highly motivational to students for regular class or independent study. Both teacher and student guides are professionally produced and include easy-to-follow directions. Illustrations identify skulls of common prey species and charts are provided for students to record the data collected. Students learn about energy transfer through food chains while observing skeletal features which identify prey animals consumed. Additional studies can be conducted to evaluate animal populations within the owl's habitat, make calculations to estimate the biomass of the prey animals, or investigate the skeletal anatomy from the taxonomic features of the prey animals. 15 student worksheets, and Teacher's guide. Grades 7 and up.

Learn concepts of air pollution and its harmful effects using one form of a common air pollutant, sulfur dioxide on experiments with plant life. This kit provides instruction, apparatus and materials to experiment with plant seedlings exposed to a sulfur dioxide atmosphere at a known concentration which produces an effect on plant life that can easily be observed within several days.
Includes 12 aluminum samples. Determine the mass and volume of each sample. The slope of the straight line that results is the density of the material. The attractive wooden holder allows the teacher to see immediately when all of the specimens have been returned!

This model shows the major structures of an animal cell
Different colors are used to easily identify the different structures of the cell
Dimensions: 12" x 15.5" x 4.5" (30 x 40 x11cm)
This model shows the major structures of an animal cell. Different colors are used to allow teachers and students to easily identify the different structures of the cell, such as the nucleus, endoplasmic reticulum, mitochondria, ribosomes, Golgi apparatus, centrioles, lysosomes, and fat vacuoles. Dimensions: 12" x 15.5" x 4.5" (30 x 40 x11cm).
Push the cart and eject the steel ball from the spring-loaded barrel. The ball falls back into the barrel of the moving car, demonstrating that the forward motion of the ball is the same as the vehicle from which it was ejected. Comes with a steel ball, release pin and cord. The barrel permits two different heights of ball flight.
